Title: Liquid crystal element
Inventor: TSUBOYAMA AKIRA
IPC: G02F1/1337
Filed: 1987-07-30
Abstract: PURPOSE:To more smoothly switch a liquid crystal by forming the 1st layer of two insulating layers of a high dielectric material, etc., and forming the 2nd layer of a low resistance dielectric material. CONSTITUTION:Transparent electrodes 2 are formed on substrates 1 of a liquid crystal cell 10 and a vertical shorting preventive layer 3 consisting of the material having a high dielectric constant or ferroelectric material and an orientation control layer 4 consisting of the low resistance dielectric material are formed on at least one transparent electrode 2. The two substrates 1 are so disposed that the electrodes 2 face each other. The ferroelectric liquid crystal FLC 5 is held in place between the substrates. Since the electric capacity of the insulating layers is thereby increased, the sure bistability is imparted to the liquid crystal and the liquid crystal is more smoothly switched.

Title: Bearing device for turbocharger
Inventor: KOI RYOJI
IPC: F16C17/10
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To provide a bearing device for a turbocharger combining noise reduc tion and improvement of turbocharger output pressure. SOLUTION: A support means 12 is composed of a noise reducing bearing 25 large in outer diameter clearance and small in inner diameter clearance, and turbocharger output pressure improving bearing 26 small in inner and outer clearance. Since whirling during the rotation of shaft 13 is sufficiently damped by the noise reducing bearing 25 large in outer diameter clearance and small in inner diameter clearance, the transmission quantity of rotational vibration to a housing 1 is suppressed to an extremely small level to reduce noise, and since the radial movable quantity of the shaft 13 is regulated by the turbocharger output pressure improving bearing 26 small in inner and outer clearance, a clearance (a tip clearance) between a compressor housing 11 and a compressor rotor 17 can be reduced by that portion to improve compressor efficiency and turbocharger output pressure.

Abstract: PURPOSE:To realize an actuator device which has extremely short step length by using a high-precision sensor as a substitute for teeth of an iron core which is fed stepwise. CONSTITUTION:The actuator is equipped with a fixed part 1A and a movable part 1B provided with windings which generate a positive and a negative force, and a sensor 3A which generates 90 deg. out-of-phase two-phase outputs A and B, and further has a signal processing circuit 6A, command generating circuit 7A, current command circuit 5A, and current control circuit 4A. Further, current values of the windings of the actuator are determined with signals (a) and (b) based upon the two-phase outputs A and B of the sensor 3A and their reversely converted signals -a and -b. Then, currents are supplied to both windings to drive the actuator positively and negatively and the force becomes zero when the currents flowing through the windings become equal in absolute value, so that the actuator stops. Consequently, the actuator is driven on the basis of the sensor signals, so the need for teeth of a stepping motor, etc., is eliminated.

Title: Color image display system
Inventor: KANEKO SHUZO
IPC: G02F1/1335
Filed: 1988-07-30
Abstract: PURPOSE:To perform color display through the use of monochrome equipment by overlapping a plotted sheet with a color filter and visualizing a color image. CONSTITUTION:Plural colors, for instance three colors R, G and B are arranged in the shape of stripes and formed by mesh and dot printing on the color filter 1. Small window-like transparent parts are provided on a sheet 2 by recording (Figure a) with a thermal head. When the sheet is overlapped with the color filter 1 (Figure b), an image by red (R) alone can be obtained as indicated in Figure (c). Recording is performed on the sheet 2 in accordance with the arrangement of the colors of the color filter 1 in such a way as parts corresponding to R alone are included whereas parts corresponding to G and B are omitted, and the transparent parts are provided thereon. In addition, when a part corresponding to more than two colors, for example, R and G arranged next to each other, is formed to be transparent, a mixed color can be obtained. Since the color filter 1 is provided on a visualizing device instead of the sheet 2 which is an image recording medium, the cost of the sheet 2 can be reduced.
